BEVERAGE PUMP.

Application filed August 19, 1927. Serial No. 214,029.-

g This invention relates to improvements in beverage pumps of the typethat is applicable to bottles and similar vessels from which beverage isdispensed, and especially those beverages of such effervescent naturethat air pressure within the container is required to be maintained tokeep the beverage in proper condition for use.

The objects of the improvements are to afford a convenient portableappliance that may be applied readily to a vessel containing thebeverage to be dispensed, such as a bottle; and to so construct thedevice that leakage from the vessel of the beverage, or the air duringsuspended operation, will be prevented.

These objects are accomplished by the construction illustrated inv theaccompanying drawings, in which Fig. 1 is a side elevation of a.structure embodying the invention applied to a bottle neck, portionsthereof being in section;

Fig. 2 is a plan view projected from Fig. 1, a portion being brokenaway; and

Fig. 3 is a side elevation of the appliance in connection with thebottle, drawn upon a reduced scale.

The characters appearing in the description refer to parts shown in thedrawings and designated thereon by corresponding characters.

The invention comprises a head 1 having chambers 2 and 3 alined thereinand separated by a perforated partition 4. A discharge spout 5 issecured in the front of the head and has communication with the chamber2 therein. In the opposite side of the head 1 is secured an air inletfixture 6 that has communication through a duct 7 with an annular recess8 made in the lower part of the head. The fixture 6 has mounted thereina valve 9 and a rubber valve seat 10 by which the air passageway 11 inthe fixture 6 is hermetically closed. The fixture 6 has also attachedthereto an air supply means which may be of any usual construction suchas one having a bulb 12 provided with inlet and outlet valves 13 and 11, with a hose connection 15 between the latter valve and the fixture 6by which air under pressure is supplied to the passage-way 11 in thefixture.

In the head 1 is positioned a centrally perforated sustaining disc 16that bears against an annular shoulder 17 in said head at the bottom ofthe chamber 2, and beneath said plate is positioned a centrallyperforated rubber valve seat 18. In the chamber-3, at

the bottom thereof and resting upon the par t1t1on 4 is a centrallyperforated rubber packing disc 19, upon the top of which bearsacentrally erforated metallic plate 20. A valve 21 is QlSPOSQtl with itsstem extending upwardly through the valve seat 18, sustaining disc 16,perforated partition l, packing disc 19 and plate 20, and has securedupon its upper end a push button 22 that has a sleeve 23 that projectsdownwardly into the chamber '3 of said head, there being a. compressionspring 24 disposed in said chamber, concentric with the stem of thevalve 21, that bears at one end against the disc 20 and at its oppositeend against the push button, so that the head 25 of said valve is heldseated thereby against the lower end of the valve seat 18.

A tubular post 26 having a valve chamber 27 in its upper end is securedin the lower end of the head 1 so that the top of said post bearsagainst the valve seat 18 and clamps the same in place. A discharge tube28 extends upwardly through the post and is secured therein so as tohave communication at its top with the valve chamber 27, there being anannular space 29 within said post surrounding the discharge tube beneaththe upper portion thereof. The post also has a passage-way 30 thataffords communication between the annular space 29 in the post and therecess 8 in the head, whereby communication between the passage-way 11in the fixture 6 and the space 29 in the post is established.

Upon the post 26 is mounted a thumb-nut 31 that has threaded relationtherewith that bears downwardly against an annular collar 32 thatloosely surrounds said post, and an annular rubber stopper 33 is securedupon the lower portion of said post in concentric relation therewith andis clamped between the collar 32 and a washer 34 that is fixed upon thelower end of the post by means of a threaded nut 35. The stopper 33 isof a size suited to be applied in the neck 36 of a. bottle 37, whichstopper is tightened in the neck when pressure is applied thereto byturning the thumb-nut 31 upon the post whereby the stopper is compressedendwise and thereby caused to expand laterally in the neck.

In utilizing the invention the device is mounted upon the bottlecontaining the beverage to be dispensed, with its discharge pipe 28projecting through the neck of the bottle into the lower part thereof,and the stopper is tightened in the neck as above described. The valve 9is then opened and the air supply means is actuated by manipulating thebulb in the usual manner whereby air under pressure is supplied to thebottle. The valve 9 is then tightly closed so as to prevent retractionof the air thus supplied. By pressing downwardly upon the push button22, the head 25 of the valve 21 is lowered from its seat 18, whereuponthe liquid in the vessel, due to the air pressure in the bottle, isforced through the discharge tube 28 into the chamber 2 from whence itflows through the spout. The packing disc 19 fits snugly about the stemof the valve 21 and thus prevents escapement of the liquid into thechamber 3. Upon releasing the button, the head 25 of the valve isreseated by the action of the spring 24, and the outflow of liquid isstopped.

What I claim is An appliance of the class described including a headhaving two alined chambers therein, there being a perforated partitiontherebetween, a perforated sustaining disc in said head at the lower endof the lowermost of said chambers; a perforated rubber valve seatbeneath and bearing against said disc; a packing member in the bottom ofthe uppermost of and having a sleeve extending into and closmunicationwith said lowermost chamber therein; a tubular post having a valvechamber in its top, the upper end of said post being secured in thelower end of said head and clamping said valve seat in place; adischarge pipe extending upwardly into said post with its upper endsecured therein and having communication with the valve chamber therein,there being an annular space in said post surrounding said tube beneaththe upper portion thereof; a valve controlled air supply means inconnection with said head and having communication with said annularspace in said post, there being a passage-way in said head and in saidpost affording communication therebetween; and a stopper fixture on saidpost for mounting the appliance upon a vessel.

In testimony whereof I afiix my signature.
